Improvement in filtering-faucets

GEORGE HILLEGASS, OF PHILADELPHIA, PENNSYLVANIA.

IMIROVEMENT IN FlLTERlNG- FAUCETS.

Specification forming part of Letters Patent No. 54,347, dated May 1, 1866.

. ing is a full, clear, and exact description of the same, reference being made to the annexed drawings, iliade part of this speciiication, in which- Figure lis a perspective view of the spigot. Fig. 2 is a longitudinal section, showing the faucet when closed. Fig. 3 is a similar section, showing the faucet when open. Fig. 4 shows the arrangement of the screw in the spigot. Fig. 5 shows the arrangement of the felt when the faucet is used as a iilter.

In the different views the same letters refer to identical parts.

A represents the tube of the faucet, which is of ordinary construction.A B is the spigot, of the general external form, having an opening through it in usual form. This spigot I make hollow and iinish it in two parts.

C represents a four-sided section cut out of the barrel of the spigot, of one-half of the circumference thereof, and cut with a dovetail, so as to slide out and in on one side, and when in to iit snugly in its place.

The dovetailed slide C is slightly cut away at its ends, so as to allow a narrow space, D, to receive a piece of felt, E, or screen E', passing across the chamber in the spigot and perfectly separating it into two parts. lThrough this iilter or screen the iiuid flowing through the spigot must pass. Whenever the duid in passing has deposited its impurities upon the face ofthe lter or screen so as to impede the iiow, by removing the spigot in the faucet, the flow being then from the opposite side of the lter or screen, these impurities will be immediately washed away and their proper action restored.

As a filter, felt, I think, is at once the cheapest and most eifective. The screen is intended for larger substances, such as the hops in ale,

material, E, or screen E across the chamber,`

through which the fluid must flow in passing through the faucet, substantially in the manner and for the purpose set forth. l

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE HILLEGASS.
